Explanation: What are Qi wireless phone chargers?

Qi wireless phone chargers are a convenient way to charge your smartphone or other devices without connecting them to a charging cable. This way, you avoid messing with cords and plugs, and it also looks a lot less messy in the house. Wireless charging is only possible with smartphones that are equipped with Qi technology.

The technology behind wireless charging is electromagnetic induction. When you put your phone on the charging station, the device’s coils and the charger move, which generates a magnetic field. The moving electrons are the electricity that charges the battery of your smartphone. Connecting your phone to a cable and the power socket is no longer necessary. You do connect the charging station itself to a cable that is connected to the socket.

Why Wireless Charging?

The answer is these below three points:


Connecting to a wireless charger is faster than connecting cables. You put your phone on the charger, and it will be charged immediately. So you don’t have to empty your other hand to connect a cable. Wireless chargers also protect your phone against damage brought on by plugging and unplugging a cable repeatedly. They are a lot more potent than charging wires, which may wear out at any stage.

Devices Always Charged

Imagine your iPhone or Samsung phone’s battery getting a boost every time you put it down. It is possible with wireless charging. Wireless chargers are available in all sizes and shapes. Having one on your bedside table, one on your desk and even one in the car makes it easy to keep even the most used device charged throughout the day.


A wireless charger works just as fast as a conventional charger. A 5W charging station charges your smartphone just as quickly as the 5W / 1A wall charger that usually comes with your smartphone.

How Does Wireless Charging Work?

Before explaining the pros and cons of wireless charging, it is useful to explain how wireless charging exactly works. Wireless charging is – in short – charging without a cable between the smartphone and the charger. The smartphone charges with induction. It means that electrical voltage is generated at the wireless charger via magnetism, emitted by the wireless charger via an electromagnetic field. Smartphones with the mobile charging function absorb this electromagnetic field. It is how the battery charges.

The Benefits Of Wireless Charging:


The incredible thing about wireless charging is you may always immediately charge your smartphone, wherever you are. You have to put your phone down, and the battery will start charging. This way, it is always charged when you are not using it. Without cables, without clutter, without waiting.


Using a wireless charging pad on your bedside table, you can make sure your phone has sufficient power for the majority of the day.


A charging stand on your desk gives your phone a boost while you work.


Wireless car chargers keep battery levels high while you drive.

On The Way

With a wireless power bank or wireless external battery, you can charge your device free of wires wherever you are.

Suitable for use with a case


While wireless charging requires a physical connection between a phone and the charger, most charging stations charge through thin plastic phone cases up to 3mm thick. You do not have to remove the cover from your smartphone for charging.

Accurate Confirmation

Your smartphone starts charging as soon as it makes contact with the charger, without having to connect a cable with a specific connector. You can place it however you want, horizontally, vertically, and everything in between. There is always a wireless charging solution perfect for your lifestyle, from wireless charging stations to portable power banks.

Highest Load Speeds

Is your wireless charger fast enough?

Ensure your wireless charging pad is compatible with your phone so that your device charges at the fastest possible speeds. There are currently many wireless chargers available with 15W output power, but these chargers may not match your device. For example, the BOOST ↑ UP ™ 7.5W Wireless Charging Pad is optimized for the new iPhone X, iPhone 8 Plus, and iPhone 8. Simultaneously, there are 15W charging solutions on the market that will only charge these new iPhone models at 5W instead of 7.5 W. Samsung Galaxy smartphones can be charged wirelessly at 9 W when using a wireless charging pad compatible with the Samsung Galaxy. So compatibility is essential if you want to enable faster charging!

What to look for when buying a Qi wireless phone charger?

Charging Speed: Time is precious, and you can’t always afford to sit around and wait for your phone to charge. It is where a fast charging option makes all the difference. The iPhone has a standard fast charging speed of 7.5W, but Android devices have more, so if you have one of those, choose a charger that turns out 9W.

Compatibility: Most newer phones come with built-in wireless charging capabilities. Before going for a wireless charger, make sure it is suitable for your model. Even if you buy a “fast wireless charging” option, but your phone doesn’t support it, you can still charge most Qi-enabled devices at an average speed. Also, check that the charger fits your phone case, so you don’t have to pry it off every time you want to charge it.

Design: Cordless phone chargers come in a variety of designs and meet different needs. Good chargers can charge phones in the horizontal or vertical direction, for example, while car chargers allow you to charge your phone while on the move.

A wireless charger is also called a QI charger or Qi wireless phone chargers. It has to do with the technology behind it. Qi wireless phone chargers use induction. You read that right: the same technology that you might use at home to heat your pans! It means that energy is created using magnetism, in this case, to charge your mobile as quickly as possible. Your charger will start working as soon as you put your phone on it, so your battery will quickly return to 100%. For example, a Samsung wireless charger ensures the full battery of your device in no time.

Not every phone is suitable for wireless chargers, so always check in advance whether your smartphone is suitable for this new technology. Some smartwatches and tablets are also suitable, and you can always request this at the point of sale of your device.
